|Title:||A new flow regime in a Taylor-Couette flow||Authors:||Lim, T.T.
|Issue Date:||1998||Citation:||Lim, T.T.,Chew, Y.T.,Xiao, Q. (1998). A new flow regime in a Taylor-Couette flow. Physics of Fluids 10 (12) : 3233-3235. ScholarBank@NUS Repository.||Abstract:||In this Brief Communication, we report a new finding on a Taylor-Couette flow in which the outer cylinder is stationary and the inner cylinder is accelerated linearly from rest to a desired speed. The results show that when the acceleration (dRe/dt) is higher than a critical value of about 2.2s-1, there exists a new flow regime in which the flow pattern shows remarkable resemblance to regular Taylor vortex flow but is of shorter wavelength. However, when the acceleration is lower than 2.2 s-1, a wavy flow is found to occur for the same Reynolds number range. To our knowledge, this is probably the first time that such a phenomenon has been observed. For completeness, the case of a decelerating cylinder is also investigated, and the results are found to be almost the same. © 1998 American Institute of Physics.||Source Title:||Physics of Fluids||URI:||http://scholarbank.nus.edu.sg/handle/10635/92651||ISSN:||10706631|
